8 Claims. (01. 121-2) v This invention relates to a bell ringing devicefor locomotives, the general object of the invention being to provideautomatic means for ringing the bell when the locomotive is in motion,the ringing ceasing when the locomotive is. not I in motion, whereby theringing of .the bell is not left to the action of the engineer.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings whereinv like characters denote like or'corresponding parts throughout the several views, and in which:--

, Figure 1 is an elevation of the front part of a locomotive, showingthe invention appliedthereto.

Figure 2 is a vertical sectional view through the invention.

4 In these drawings, the device is shown'at A and is located on anysuitable part of the front part of the locomotive and consists of ahollow base 1 forming an air chamber 2 which has an opening in one endthereof closed by a plug 3. A pipe 4 is in communication with the otherend of the chamber and leads to the pneumatic bell ringer B of the bellC. The bell ringer is of the usual or any desired type. A cylinder 6 hasa reduced part 7 provided with a flange 8 which is bolted to the top ofthe base 1, as shown at 9. A sheet 10 of asbestos packing is locatedbetween the parts to retard transfer of ,heat from the base to the lowerpart of the cylinder. The cylinder has a head llbolted theretoand apiston 12 is located in the cylinder and has a stem 13 depending intothe reduced part '7. A valve chamber 14 is formed in a part of the wallof the cylinder 6 and is in communication with the cylinder through theport 15, the chamber having a reduced lower part 16, the junction ofwhichwith the large part forms a valve seat for a ball valve 1'7. A pipe18 connects the large part of the valve chamber 14 with either end ofeither cylinder 19 of the locomotive and a pipe 20 connects the lowerend of the small part 16 with the steam supply pipe 21 of the locomotiveand a pipe 22 connects the cylinder, at the point of junction of thelower part thereof with the reduced part 7, with the exhaust passage ofa locomotive cylinder, or this drain pipe 22 may exhaust at any other econvenient point.

An air cylinder 23 is bolted to the top of the cylinder 23 for thepassage of a lever 38 which throttle is opened, 'steam' will passthrough the chamber 14 of the cylinder 6. Y v steam going to thelocomotive cylinders will cause the locomotive to move in theusual'manner and base 1, as shown at 24, and has a sheet 25 of asbestosor the like insulating it from the baseand this cylinder has a head 26bolted thereto and a passage 27 connects the lower part of the cylinderH with the chamber 2. A pipe 28 connects the upper part of the cylinder23 with the air reservoir 5 of the locomotive. A sleeve 29 is located inthe lower part of the cylinder 23 and the upper end thereof forms avalve seat for'a ball valve 30 which separates the upper end of thepassage 27 from the pipe 28, the sleeve having a port 31 therein whichregisters with the upper end of the passage 27. Acup'member'32, formedof asbestos or the like, seats on a steel tip 33 and a I bolt 34 passesthrough a sleeve 35, through a hole 7 in the cup member into the tip andthese parts form a stem for the valve 30. An opening 36 is formed in thelower part of the cylinder Band anopening 37 is formed in the lower partof the ha'sa notch 39 adjacent one end thereof which 5 fits over afulcrum projection 40 on a plate 41 fastened to the top of the base by ascrew 42.

'Thus it will be seen'that when the locomotive steam pipe 21 into thecylinders 19 of the 1000- o motive and some of this steam will passthrough the. pipe 20 into the lower part of the valve Of course, the

the steam passing through the pipe 20 will lift 'the valve 17 so that'the steam will pass through the chamber l4and through port 15 into thecylinder 6 and the pressure of this steam in the cylinder 6 will causethe piston 12 to move downwardly so that its stem will rock the lever 38so 'as to raise the short end thereof so that the valve stem in thecylinder 23 is raised, which I 'unseatsthe valve 30. When this occurs,air from the reservoir 5 of the locomotive passes through the pipe 28into the cylinder 23, by the valve 30 and through the port 31 andpassage 27 into the position described and illustrated in Figure 2,

and air passes to the pneumatic bell ringer. When the throttle of thelocomotive is closed,

the valve 1'7 seats itself, by gravity. Steam or compression in thelocomotive cylinder on the forward stroke of the piston enters andpasses through the valve chamber 14 and through the port 15 to thecylinder. 6, and action as described above takes place. On the backwardstroke of the locomotive piston and/or when no pressure is exerted onthe piston 12, air from the main reservoir, acting on the valve 30,seats the same, shutting off the supply of -air-to--the reservoir 2. rThe reservoir -2 is so proportioned as to furnish enough head of airpressure for the operation of the pneumatic bell ringer during "thealternate opening and closing of the ball check 30, during such time asthe locomotive may be drifting and not working-steam.

When no further pressure is exerted .onthe piston 12, either by livesteam 'fromthe throttle or by compression in the loeomotiveoylindefhaving been reduced to zero through the locomotive and consequentlypiston stopping, then theair pressure, acting on the valve -,30, .seatsthe :same ;--and cuts off the air supply zto- 'the reservoir 2.
